The invention discloses a magnetorheological damper control method and system and a vehicle suspension system. The control system comprises a fuzzy PID controller and a parameter optimizer. The fuzzy PID controller comprises a fuzzy logic controller and a PID controller. Firstly, a fuzzy logic controller determines PID parameters of a PID controller by utilizing a fuzzy rule according to the deviation between a set value and an actual output value of damping force output by the magnetorheological damper; and then, the parameter optimizer optimizes the PID parameters output by the fuzzy logic controller by adopting a grey wolf algorithm to obtain the optimal PID parameters. And finally, the PID controller can adjust the parameters according to the optimization result of the parameter optimizer, and the magneto-rheological damper is controlled through the fuzzy PID controller subjected to parameter adjustment, so that the performance of the fuzzy PID controller is effectively improved, and the riding comfort of the vehicle is further improved.
